PET felt is an increasingly popular choice in modern interior design – and for good reason. It is a versatile, lightweight and aesthetically pleasing material that effectively absorbs sound, and is also environmentally friendly. If you are looking for an acoustic solution for your home, office, restaurant, school or any public space – PET felt panels are the ideal solution.

What is PET felt?

PET (polyethylene terephthalate) felt is made from recycled plastic bottles, making it a sustainable material. In the production process, the plastic is ground into flakes, which are then melted, pressed and shaped into a dense but flexible felt. The finished product is light, strong, resistant to moisture, does not contain harmful substances, and comes in a wide range of colors.

Acoustic properties of PET felt

Thanks to its porous structure, PET felt is an excellent sound absorber – the sound absorption coefficient (NRC) can be up to 0.90. This means that it significantly reduces echo and noise in the room. It achieves even better results when placed with a small distance from the wall, which further increases its efficiency. This makes it ideal for spaces where acoustics are important – schools, kindergartens, restaurants, offices, music studios and other public spaces.

Advantages of PET felt

  • Environmentally friendly - up to 75% of the material comes from recycled plastic

  • Durable and resistant - withstands impacts and high humidity

  • It is easy to process - simple cutting and assembly, possible custom molding

  • A rich color palette – attractive design solutions for every space

  • Minimal maintenance – dust-resistant, easy to clean

Due to its structure, PET felt is flexible, but also strong enough for long-term use. It can be cut into various shapes, bent, and perfectly fit into modern interiors, while improving the acoustics of the space.

It is this combination of modern appearance and acoustic properties that makes PET felt one of the most sought-after materials in today's architecture and interior design.
